Rules & Regulation

Umpire Decision Review System

The umpire review system will be trialled for the first time in the upcoming India-Sri Lanka series starting on July 23. England refused to use the referral system in the ongoing series against South Africa since they felt it would undermine the authority of the umpires and wanted them to remain in charge.

Each team is allowed to make three unsuccessful review requests per innings. If a review results in the umpire reversing his original decision, then the request has been successful and does not count towards the innings limit. If the umpire’s decision is unchanged, the review is unsuccessful. After three unsuccessful requests by one team, no further review requests will be allowed by that team during the current innings.

The scoreboard shall display, for the innings in progress, the number of reviews remaining available to each team.

When can a review be requested?

Only the batsman involved in a dismissal may request a review of an ‘Out’ decision and only the captain (or acting captain) of the fielding team may request a review of a ‘Not Out’ decision.
A decision concerning whether or not a batsman is dismissed that could have been referred by the onfield umpire to the TV umpire is eligible for review as soon as it is clear that the onfield umpire has chosen not to make the referral

How is the review to be requested?

The request should be made by the player making a ‘T’ sign with both forearms at head height.
The captain may consult with the bowler and other fielders or the two batsmen may consult with each other prior to deciding whether to request a review. However, such consultation will need to occur almost instantly and be very brief.

If the umpires believe that players have received input from players not on the field they may decline the request for a review.

If despite the available technology, the TV umpire is unable to answer with certainty or with reasonable confidence a particular question posed by the on-field umpire, then he should report that the replays are ‘inconclusive’. The TV umpire should not give answers conveying likelihoods or probabilities.

Dead ball

If an original decision of ‘Not Out’ is changed to ‘Out’, the ball will retrospectively be deemed to have become dead from the moment of the dismissal event. All subsequent events, including any runs scored, are ignored.

Use of technology

The following technology may be used by the TV umpire.
    - Slow motion replays from all available cameras
    - Super slow motion replays from all available cameras
    - Ultra motion camera replays from all available cameras
    - The mat (positioned accurately)
    - Sound from the stump microphones with the replays at normal speed and slow motion
    - Approved ball tracking technology (for actual ball tracking purposes only and not for predicting the potential future trajectory of the ball)
